While Microsoft has long abandoned , exclusive methods still exist for the determined user. Whether you’re preserving industrial automation, playing retro LAN games, or simply curious, this guide provides the roadmap. Remember: with great legacy power comes great responsibility – always test in a virtual environment first.
You may encounter "duplicate computer name" errors, which are common errors in the system logs when using NetBEUI on newer operating systems.

On Windows XP, these were located at:
Connect the second NIC directly to the legacy machine.
Before diving into installation, it's crucial to understand what Microsoft officially says: netbeui+for+windows+7+11+exclusive
Place netnbf.inf into the C:\Windows\inf\ directory (Note: This is a hidden folder by default).

The official Microsoft documentation clearly states: "The use of NetBIOS over IPX or NetBEUI is deprecated and not used by default. NetBIOS datagrams over TCP/IP (NBT datagrams)… is the default transport used by the Windows implementation."
However, many industrial environments face a massive challenge: multi-million dollar CNC machines, legacy Heidelberg printing presses, and textile equipment manufactured in the 1990s rely entirely on NetBEUI for network file transfers. Replacing this legacy hardware is economically impossible. You may encounter "duplicate computer name" errors, which
